This is an old question with valuable answers, but I was still a bit confused until I found a real life example that shows the issue with 3NF. Maybe not suitable for an 8-year old child but hope it helps.

Tomorrow I'll meet the teachers of my eldest daughter in one of those quarterly parent/teachers meetings. Here's what my diary looks like (names and rooms have been changed):

Teacher   | Date             | Room
----------|------------------|-----
Mr Smith  | 2018-12-18 18:15 | A12 
Mr Jones  | 2018-12-18 18:30 | B10 
Ms Doe    | 2018-12-18 18:45 | C21 
Ms Rogers | 2018-12-18 19:00 | A08 

There's only one teacher per room and they never move. If you have a look, you'll see that: (1) for every attribute Teacher, Date, Room, we have only one value per row. (2) super-keys are: (Teacher, Date, Room), (Teacher, Date) and (Date, Room) and candidate keys are obviously (Teacher, Date) and (Date, Room).

_{(Teacher, Room) is not a superkey because I will complete the table next quarter and I may have a row like this one (Mr Smith did not move!):}

Teacher  | Date             | Room
---------|------------------| ----
Mr Smith | 2019-03-19 18:15 | A12

What can we conclude? (1) is an informal but correct formulation of 1NF. From (2) we see that there is no "non prime attribute": 2NF and 3NF are given for free.

My diary is 3NF. Good! No. Not really because no data modeler would accept this in a DB schema. The Room attribute is dependant on the Teacher attribute (again: teachers do not move!) but the schema does not reflect this fact. What would a sane data modeler do? Split the table in two:

Teacher   | Date
----------|-----------------
Mr Smith  | 2018-12-18 18:15
Mr Jones  | 2018-12-18 18:30
Ms Doe    | 2018-12-18 18:45
Ms Rogers | 2018-12-18 19:00

And

Teacher   | Room
----------|-----
Mr Smith  | A12
Mr Jones  | B10
Ms Doe    | C21
Ms Rogers | A08

But 3NF does not deal with prime attributes dependencies. This is the issue: 3NF compliance is not enough to ensure a sound table schema design under some circumstances.

With BCNF, you don't care if the attribute is a prime attribute or not in 2NF and 3NF rules. For every non trivial dependency (subsets are obviously determined by their supersets), the determinant is a complete super key. In other words, nothing is determined by something else than a complete super key (excluding trivial FDs). (See other answers for formal definition).

As soon as Room depends on Teacher, Room must be a subset of Teacher (that's not the case) or Teacher must be a super key (that's not the case in my diary, but thats the case when you split the table).

To summarize: BNCF is more strict, but in my opinion easier to grasp, than 3NF:

• in most of cases, BCNF is identical to 3NF;
• in other cases, BCNF is what you think/hope 3NF is.

Why not just use the literal characters?

fig.gca().set_xlabel("wavelength, (Å)")
fig.gca().set_ylabel("?")

You might have to add this to the file if you are using python 2:

# -*- coding: utf-8 -*-
from __future__ import unicode literals  # or use u"unicode strings"

It might be easier to define constants for characters that are not easy to type on your keyboard.

ANGSTROM, LAMDBA = "Å?"

Then you can reuse them elsewhere.

fig.gca().set_xlabel("wavelength, (%s)" % ANGSTROM)
fig.gca().set_ylabel(LAMBDA)

For the non-selected radio buttons, flag them as disabled. This prevents them from responding to user input and clearing out the checked radio button. For example:

<input type="radio" name="var" checked="yes" value="Yes"></input>
<input type="radio" name="var" disabled="yes" value="No"></input>

I believe this would also work:

select count(distinct switch_id)   
  from [email protected]  
 where 
   dealer_name =  'XXXX'    
   and (creation_date BETWEEN add_months(trunc(sysdate,'mm'),-1) and  trunc(sysdate, 'mm'))

It has the advantage of using BETWEEN which is the way the OP used his date selection criteria.

Let's keep them simple, shall we. First off, using pure HTML + CSS:

<div id="emotion">
    <input type="radio" name="emotion" id="sad" />
        <label for="sad"><img src="sad_image.png" alt="I'm sad" /></label>

    <input type="radio" name="emotion" id="happy" />
        <label for="happy"><img src="happy_image.png" alt="I'm happy" /></label>
</div>

This will degrade nicely if there's no JavaScript. Use id and for attributes to link up the label and radiobutton so that when the image is selected, the corresponding radiobutton will be filled. This is important because we'll need to hide the actual radiobutton using JavaScript. Now for some jQuery goodness. First off, creating the CSS we'll need:

.input_hidden {
    position: absolute;
    left: -9999px;
}

.selected {
    background-color: #ccc;
}

#emotion label {
    display: inline-block;
    cursor: pointer;
}

#emotion label img {
    padding: 3px;
}

Now for the JavaScript:

$('#emotion input:radio').addClass('input_hidden');
$('#emotion label').click(function(){
    $(this).addClass('selected').siblings().removeClass('selected');
});

The reason why we're not using display: none here is for accessibility reasons. See: http://www.jsfiddle.net/yijiang/Zgh24/1 for a live demo, with something more fancy.

I have written a pretty fast method in c# which beats the hell out of the Regex. It is hosted in an article on CodeProject.

Its advantages are, among better performance the ability to replace named and numbered HTML entities (those like & and &203;) and comment blocks replacement and more.

Please read the related article on CodeProject.

Thank you.

When I tried these steps I kept getting error:

1. Search for "Turn windows features on or off"
2. Check "Internet Information Services"
3. Check "World Wide Web Services"
4. Check "Application Development Features"
5. Enable all items under this

Then i looked at event viewer and saw this error:Unable to install counter strings because the SYSTEM\CurrentControlSet\Services\ASP.NET_64\Performance key could not be opened or accessed. The first DWORD in the Data section contains the Win32 error code.

To fix the issue i manually created following entry in registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ASP.NET_64\Performance

and followed these steps:

1. Search for "Turn windows features on or off"
2. Check "Internet Information Services"
3. Check "World Wide Web Services"
4. Check "Application Development Features"
5. Enable all items under this

Send User to Settings With located Package, example for WRITE_SETTINGS permission:

(Can't comment, not enough reputation, but here is a modified version that worked for me)

To @HamedMP error about the No default session is registered you can use InteractiveSession to get rid of this error: https://www.tensorflow.org/versions/r0.8/api_docs/python/client.html#InteractiveSession

And to @NumesSanguis issue with Image.show, you can use the regular PIL .show() method because fromarray returns an image object.

I do both below (note I'm using JPEG instead of PNG):

import tensorflow as tf
import numpy as np
from PIL import Image

filename_queue = tf.train.string_input_producer(['my_img.jpg']) #  list of files to read

reader = tf.WholeFileReader()
key, value = reader.read(filename_queue)

my_img = tf.image.decode_jpeg(value) # use png or jpg decoder based on your files.

init_op = tf.initialize_all_variables()
sess = tf.InteractiveSession()
with sess.as_default():
    sess.run(init_op)

# Start populating the filename queue.

coord = tf.train.Coordinator()
threads = tf.train.start_queue_runners(coord=coord)

for i in range(1): #length of your filename list
  image = my_img.eval() #here is your image Tensor :) 

Image.fromarray(np.asarray(image)).show()

coord.request_stop()
coord.join(threads)

First, remove the float attribute on the inner divs. Then, put text-align: center on the main outer div. And for the inner divs, use display: inline-block. Might also be wise to give them explicit widths too.

<div style="margin: auto 1.5em; display: inline-block;">
  <img title="Nadia Bjorlin" alt="Nadia Bjorlin" src="headshot.nadia.png"/>
  <br/>
  Nadia Bjorlin
</div>

You can use anonymous types for example:

  var empData = from res in _db.EMPLOYEEs
                where res.EMAIL == givenInfo || res.USER_NAME == givenInfo
                select new { res.EMAIL, res.USER_NAME };

The Tumbler V2 API provides a pure JSON response but requires jumping through a few hoops:

1. Register an application
2. Get your "OAuth Consumer Key" which you'll find when editing your application from the apps page
3. Use any of the methods that only require an API Key for authentication as this can be passed in the URL, e.g. posts
4. Enjoy your JSON response!

Example URL: http://api.tumblr.com/v2/blog/puppygifs.tumblr.com/posts/photo?api_key=YOUR_KEY_HERE

Result showing tree structure in Fiddler:

LIMIT limit OFFSET offset will work.

But you need a stable ORDER BY clause, or the values may be ordered differently for the next call (after any write on the table for instance).

SELECT *
FROM   msgtable
WHERE  cdate = '2012-07-18'
ORDER  BY msgtable_id  -- or whatever is stable 
LIMIT  10
OFFSET 50;  -- to skip to page 6

Use standard-conforming date style (ISO 8601 in my example), which works irregardless of your locale settings.

Paging will still shift if involved rows are inserted or deleted or changed in relevant columns. It has to.

To avoid that shift or for better performance with big tables use smarter paging strategies:

• Optimize query with OFFSET on large table

To run batch files using java if that's you're talking about...

String path="cmd /c start d:\\sample\\sample.bat";
Runtime rn=Runtime.getRuntime();
Process pr=rn.exec(path);`

This should do it.

ngRepeat creates a copy of the array when it applies a filter, so you can't use the source array to reference only the filtered elements.

In your case, in may be better to apply the filter inside of your controller using the $filter service:

function MainCtrl( $scope, filterFilter ) {
  // ...

  $scope.filteredData = myNormalData;

  $scope.$watch( 'myInputModel', function ( val ) {
    $scope.filteredData = filterFilter( myNormalData, val );
  });

  // ...
}

And then you use the filteredData property in your view instead. Here is a working Plunker: http://plnkr.co/edit/7c1l24rPkuKPOS5o2qtx?p=preview

If using Cpanel/WHM the location of file config.default.php is under

/usr/local/cpanel/base/3rdparty/phpMyAdmin/libraries

and you should change the $cfg['ExecTimeLimit'] = 300; to $cfg['ExecTimeLimit'] = 0;

Probably:

git pull origin master

I bumped into this problem using PHP-FPM and Apache after increasing Apache's default LimitRequestFieldSize and LimitRequestLine values.

The only reason I did this (apache says don't mess) is because Yii2 has some pjax problems with POST requests. As a workaround, I decided to increase these limits and use gigantic GET headers.

php-fpm barfed up the 500 error though.

Simplest solution

Use numpy.dot or a.dot(b). See the documentation here.

>>> a = np.array([[ 5, 1 ,3], 
                  [ 1, 1 ,1], 
                  [ 1, 2 ,1]])
>>> b = np.array([1, 2, 3])
>>> print a.dot(b)
array([16, 6, 8])

This occurs because numpy arrays are not matrices, and the standard operations *, +, -, / work element-wise on arrays. Instead, you could try using numpy.matrix, and * will be treated like matrix multiplication.

Other Solutions

Also know there are other options:

• As noted below, if using python3.5+ the @ operator works as you'd expect:

  >>> print(a @ b)
  array([16, 6, 8])
  

• If you want overkill, you can use numpy.einsum. The documentation will give you a flavor for how it works, but honestly, I didn't fully understand how to use it until reading this answer and just playing around with it on my own.

  >>> np.einsum('ji,i->j', a, b)
  array([16, 6, 8])
  

• As of mid 2016 (numpy 1.10.1), you can try the experimental numpy.matmul, which works like numpy.dot with two major exceptions: no scalar multiplication but it works with stacks of matrices.

  >>> np.matmul(a, b)
  array([16, 6, 8])
  

• numpy.inner functions the same way as numpy.dot for matrix-vector multiplication but behaves differently for matrix-matrix and tensor multiplication (see Wikipedia regarding the differences between the inner product and dot product in general or see this SO answer regarding numpy's implementations).

  >>> np.inner(a, b)
  array([16, 6, 8])
  
  # Beware using for matrix-matrix multiplication though!
  >>> b = a.T
  >>> np.dot(a, b)
  array([[35,  9, 10],
         [ 9,  3,  4],
         [10,  4,  6]])
  >>> np.inner(a, b) 
  array([[29, 12, 19],
         [ 7,  4,  5],
         [ 8,  5,  6]])
  

Rarer options for edge cases

• If you have tensors (arrays of dimension greater than or equal to one), you can use numpy.tensordot with the optional argument axes=1:

  >>> np.tensordot(a, b, axes=1)
  array([16,  6,  8])
  

• Don't use numpy.vdot if you have a matrix of complex numbers, as the matrix will be flattened to a 1D array, then it will try to find the complex conjugate dot product between your flattened matrix and vector (which will fail due to a size mismatch n*m vs n).

For those who are finding for a thread safe solution, take a look here.

Code:

UPDATE Account 
SET    sg_status = 'A'
OUTPUT INSERTED.AccountId --You only need this if you want to return some column of the updated item
WHERE  AccountId = 
(
    SELECT TOP 1 AccountId 
    FROM Account WITH (UPDLOCK) --this is what makes the query thread safe!
    ORDER  BY CreationDate 
)

List<Person> list = new ArrayList<Person>();
Criteria criteria = this.getSessionFactory().getCurrentSession().createCriteria(Person.class);
for (final Object o : criteria.list()) {
    list.add((Person) o);
}

Predicate falls under the category of generic delegates in C#. This is called with one argument and always return the boolean type. Basically, the predicate is used to test the condition - true/false. Many classes support predicate as an argument. For example, list.findall expects the parameter predicate. Here is an example of predicate.

Imagine a function pointer with the signature:

<modifier> bool delegate myDelegate<in T>(T match);

Here is the example:

Node.cs:

namespace PredicateExample
{
    class Node
    {
        public string Ip_Address { get; set; }
        public string Node_Name { get; set; }
        public uint Node_Area { get; set; }
    }
}

Main class:

using System;
using System.Threading;
using System.Collections.Generic;

namespace PredicateExample
{
    class Program
    {
        static void Main(string[] args)
        {
            Predicate<Node> backboneArea = Node =>  Node.Node_Area == 0 ;
            List<Node> Nodes = new List<Node>();
            Nodes.Add(new Node { Ip_Address = "1.1.1.1", Node_Area = 0, Node_Name = "Node1" });
            Nodes.Add(new Node { Ip_Address = "2.2.2.2", Node_Area = 1, Node_Name = "Node2" });
            Nodes.Add(new Node { Ip_Address = "3.3.3.3", Node_Area = 2, Node_Name = "Node3" });
            Nodes.Add(new Node { Ip_Address = "4.4.4.4", Node_Area = 0, Node_Name = "Node4" });
            Nodes.Add(new Node { Ip_Address = "5.5.5.5", Node_Area = 1, Node_Name = "Node5" });
            Nodes.Add(new Node { Ip_Address = "6.6.6.6", Node_Area = 0, Node_Name = "Node6" });
            Nodes.Add(new Node { Ip_Address = "7.7.7.7", Node_Area = 2, Node_Name = "Node7" });

            foreach( var item in Nodes.FindAll(backboneArea))
            {
                Console.WriteLine("Node Name " + item.Node_Name + " Node IP Address " + item.Ip_Address);
            }

            Console.ReadLine();
        }
    }
}

I was in a situation where Linq binding was not available and had to expand lambda explicitly. It resulted in a simple function:

public static T KeyByValue<T, W>(this Dictionary<T, W> dict, W val)
{
    T key = default;
    foreach (KeyValuePair<T, W> pair in dict)
    {
        if (EqualityComparer<W>.Default.Equals(pair.Value, val))
        {
            key = pair.Key;
            break;
        }
    }
    return key;
}

Call it like follows:

public static void Main()
{
    Dictionary<string, string> dict = new Dictionary<string, string>()
    {
        {"1", "one"},
        {"2", "two"},
        {"3", "three"}
    };

    string key = KeyByValue(dict, "two");       
    Console.WriteLine("Key: " + key);
}

Works on .NET 2.0 and in other limited environments.

Why would you use it if you already knew the class and were going to cast it? Why not just do it the old fashioned way and make the class like you always make it? There's no advantage to this over the way it's done normally. Is there a way to take the text and operate on it thusly:

label1.txt = "Pizza" 
Magic(label1.txt) p = new Magic(lablel1.txt)(arg1, arg2, arg3);
p.method1();
p.method2();

If I already know its a Pizza there's no advantage to:

p = (Pizza)somefancyjunk("Pizza"); over
Pizza p = new Pizza();

but I see a huge advantage to the Magic method if it exists.

In case you're dealing with <a> tag, and you want to interrupt going to the default href you should use this instead.

Go to default url (yahoo):

<a href="https://yahoo.com" onclick="location.href='https://google.com';"> 

Go to new url (google) onclick:

<a href="https://yahoo.com" onclick="this.href='https://google.com';">

By using this you're interrupting the current browser onclick event and changing href before continuing to default behaviour of <a href='...

Very likely, you just need to change the slash/blackslash: from

 \home\sivakumar\Desktop\test.sql

to

 /home/sivakumar/Desktop/test.sql

So the command would be:

source /home/sivakumar/Desktop/test.sql

This is a simple way to create a progressbar

# setting up toolbar [-------------------------------------]
sys.stdout.write("[%s]"%(("-")*toolbar_width))
sys.stdout.flush()
# each hash represents 2 % of the progress
for i in range(toolbar_width):
    sys.stdout.write("\r") # return to start of line
    sys.stdout.flush()
    sys.stdout.write("[")#Overwrite over the existing text from the start 
    sys.stdout.write("#"*(i+1))# number of # denotes the progress completed 
    sys.stdout.flush()
    time.sleep(0.1)

Make sure JAVA_HOME is set and the path in environment variables. The PATH should be able to find the keytools.exe

Open “Windows search” and search for "Environment Variables"

Under “System variables” click the “New…” button and enter JAVA_HOME as “Variable name” and the path to your Java JDK directory under “Variable value” it should be similar to this C:\Program Files\Java\jre1.8.0_231

Sometimes the ternary operator is the best way to get the job done. In particular when you want the result of the ternary to be an l-value.

This is not a good example, but I'm drawing a blank on somethign better. One thing is certian, it is not often when you really need to use the ternary, although I still use it quite a bit.

const char* appTitle  = amDebugging ? "DEBUG App 1.0" : "App v 1.0";

One thing I would warn against though is stringing ternaries together. They become a real
problem at maintennance time:

int myVal = aIsTrue ? aVal : bIsTrue ? bVal : cIsTrue ? cVal : dVal;

EDIT: Here's a potentially better example. You can use the ternary operator to assign references & const values where you would otherwise need to write a function to handle it:

int getMyValue()
{
  if( myCondition )
    return 42;
  else
    return 314;
}

const int myValue = getMyValue();

...could become:

const int myValue = myCondition ? 42 : 314;

Which is better is a debatable question that I will choose not to debate.

try This. Put Bellow Code In Button.

let alert = UIAlertController(title: "Your_Title_Text", message: "Your_MSG", preferredStyle: UIAlertControllerStyle.alert)
alert.addAction(UIAlertAction(title: "Your_Text", style: UIAlertActionStyle.default, handler: nil))
self.present(alert, animated:true, completion: nil)

Your first option is the good one. It's the least problematic one and you've already found the correct reasons why you couldn't use the other options.

By the way, your heading IS explicitly associated with the <ul> : it's right before the list! ;)

edit: Steve Faulkner, one of the editors of W3C HTML5 and 5.1 has sketched out a definition of an lt element. That's an unofficial draft that he'll discuss for HTML 5.2, nothing more yet.

The standard states that prompting can be controlled by canceling the beforeunload event or setting the return value to a non-null value. It also states that authors should use Event.preventDefault() instead of returnValue, and the message shown to the user is not customizable.

As of 69.0.3497.92, Chrome has not met the standard. However, there is a bug report filed, and a review is in progress. Chrome requires returnValue to be set by reference to the event object, not the value returned by the handler.

It is the author's responsibility to track whether changes have been made; it can be done with a variable or by ensuring the event is only handled when necessary.

window.addEventListener('beforeunload', function (e) {_x000D_
    // Cancel the event as stated by the standard._x000D_
    e.preventDefault();_x000D_
    // Chrome requires returnValue to be set._x000D_
    e.returnValue = '';_x000D_
});_x000D_
    _x000D_
window.location = 'about:blank';

The most simple way is using type casting:

public char toChar(int c) {
    return (char)c;
}

When we apply local url, ErrorDocument directive expect the full path from DocumentRoot. There fore,

 ErrorDocument 404 /yourfoldernames/errors/404.html

For generic entries:

x = np.array([11, 2, 3, 5, 3, 2, 16, 10, 10, 3, 11, 4, 5, 16, 3, 11, 4])
n = {i:len([j for j in np.where(x==i)[0]]) for i in set(x)}
ix = {i:[j for j in np.where(x==i)[0]] for i in set(x)}

Will output a count:

{2: 2, 3: 4, 4: 2, 5: 2, 10: 2, 11: 3, 16: 2}

And indices:

{2: [1, 5],
3: [2, 4, 9, 14],
4: [11, 16],
5: [3, 12],
10: [7, 8],
11: [0, 10, 15],
16: [6, 13]}

In an attempt to find a way to make the target cell for the intersect method a name table array, I stumbled across a simple way to run something when ANY cell or set of cells on a particular sheet changes. This code is placed in the worksheet module as well:

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Cells.Count > 0 Then
'mycode here
end if
end sub

Well, I don't know how dynamic this is is, but sometimes this might save your debugging life:

var daString="<div id=\'block\' class=\'block\'><div class=\'block-2\'></div></div>";
var daParent=document.getElementById("the ID of whatever your parent is goes in here");
daParent.innerHTML=daString;

"Rat javascript" If I did it correctly. Works for me directly when the div and contents are not themselves dynamic of course, or you can even manipulate the string to change that too, though the string manipulating is complex than the "element.property=bla" approach, this gives some very welcome flexibility, and is a great debugging tool too :) Hope it helps.

How to make a button call PHP?

I don't care if the page reloads or displays the results immediately;

Good!

Note: If you don't want to refresh the page see "Ok... but how do I Use Ajax anyway?" below.

I just want to have a button on my website make a PHP file run.

That can be done with a form with a single button:

<form action="">
  <input type="submit" value="my button"/>
</form>

That's it.

Pretty much. Also note that there are cases where ajax is really the way to go.

That depends on what you want. In general terms you only need ajax when you want to avoid realoading the page. Still you have said that you don't care about that.

Why I cannot call PHP directly from JavaScript?

If I can write the code inside HTML just fine, why can't I just reference the file for it in there or make a simple call for it in Javascript?

Because the PHP code is not in the HTML just fine. That's an illusion created by the way most server side scripting languages works (including PHP, JSP, and ASP). That code only exists on the server, and it is no reachable form the client (the browser) without a remote call of some sort.

You can see evidence of this if you ask your browser to show the source code of the page. There you will not see the PHP code, that is because the PHP code is not send to the client, therefore it cannot be executed from the client. That's why you need to do a remote call to be able to have the client trigger the execution of PHP code.

If you don't use a form (as shown above) you can do that remote call from JavaScript with a little thing called Ajax. You may also want to consider if what you want to do in PHP can be done directly in JavaScript.

How to call another PHP file?

Use a form to do the call. You can have it to direct the user to a particlar file:

<form action="myphpfile.php">
  <input type="submit" value="click on me!">
</form>

The user will end up in the page myphpfile.php. To make it work for the current page, set action to an empty string (which is what I did in the example I gave you early).

I just want to link it to a PHP file that will create the permanent blog post on the server so that when I reload the page, the post is still there.

You want to make an operation on the server, you should make your form have the fields you need (even if type="hidden" and use POST):

<form action="" method="POST">
  <input type="text" value="default value, you can edit it" name="myfield">
  <input type="submit" value = "post">
</form>

What do I need to know about it to call a PHP file that will create a text file on a button press?

see: How to write into a file in PHP.

How do you recieve the data from the POST in the server?

I'm glad you ask... Since you are a newb begginer, I'll give you a little template you can follow:

<?php
    if ($_SERVER['REQUEST_METHOD'] === 'POST')
    {
        //Ok we got a POST, probably from a FORM, read from $_POST.
        var_dump($_PSOT); //Use this to see what info we got!
    }
    else
    {
       //You could assume you got a GET
       var_dump($_GET); //Use this to see what info we got!
    }
 ?>
 <!DOCTYPE html>
 <html lang="en">
   <head>
     <meta char-set="utf-8">
     <title>Page title</title>
   </head>
   <body>
     <form action="" method="POST">
       <input type="text" value="default value, you can edit it" name="myfield">
       <input type="submit" value = "post">
     </form>
   </body>
 </html>

Note: you can remove var_dump, it is just for debugging purposes.

How do I...

I know the next stage, you will be asking how to:

1. how to pass variables form a PHP file to another?
2. how to remember the user / make a login?
3. how to avoid that anoying message the appears when you reload the page?

There is a single answer for that: Sessions.

I'll give a more extensive template for Post-Redirect-Get

<?php
    if ($_SERVER['REQUEST_METHOD'] === 'POST')
    {
        var_dump($_PSOT);
        //Do stuff...
        //Write results to session
        session_start();
        $_SESSION['stuff'] = $something;
        //You can store stuff such as the user ID, so you can remeember him.
        //redirect:
        header('Location: ', true, 303);
        //The redirection will cause the browser to request with GET
        //The results of the operation are in the session variable
        //It has empty location because we are redirecting to the same page
        //Otherwise use `header('Location: anotherpage.php', true, 303);`
        exit();
    }
    else
    {
        //You could assume you got a GET
        var_dump($_GET); //Use this to see what info we got!
        //Get stuff from session
        session_start();
        if (array_key_exists('stuff', $_SESSION))
        {
           $something = $_SESSION['stuff'];
           //we got stuff
           //later use present the results of the operation to the user.
        }
        //clear stuff from session:
        unset($_SESSION['stuff']);
        //set headers
        header('Content-Type: text/html; charset=utf-8');
        //This header is telling the browser what are we sending.
        //And it says we are sending HTML in UTF-8 encoding
    }
 ?>
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta char-set="utf-8">
    <title>Page title</title>
  </head>
  <body>
    <?php if (isset($something)){ echo '<span>'.$something.'</span>'}?>;
    <form action="" method="POST">
      <input type="text" value="default value, you can edit it" name="myfield">
      <input type="submit" value = "post">
    </form>
  </body>
</html>

Please look at php.net for any function call you don't recognize. Also - if you don't have already - get a good tutorial on HTML5.

Also, use UTF-8 because UTF-8!

Notes:

I'm making a simple blog site for myself and I've got the code for the site and the javascript that can take the post I write in a textarea and display it immediately.

If are you using a CMS (Codepress, Joomla, Drupal... etc)? That make put some contraints on how you got to do things.

Also, if you are using a framework, you should look at their documentation or ask at their forum/mailing list/discussion page/contact or try to ask the authors.

Ok... but how do I Use Ajax anyway?

Well... Ajax is made easy by some JavaScript libraries. Since you are a begginer, I'll recomend jQuery.

So, let's send something to the server via Ajax with jQuery, I'll use $.post instead of $.ajax for this example.

<?php
    if ($_SERVER['REQUEST_METHOD'] === 'POST')
    {
        var_dump($_PSOT);
        header('Location: ', true, 303);
        exit();
    }
    else
    {
        var_dump($_GET);
        header('Content-Type: text/html; charset=utf-8');
    }
 ?>
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta char-set="utf-8">
    <title>Page title</title>
    <script>
        function ajaxmagic()
        {
            $.post(                             //call the server
                "test.php",                     //At this url
                {
                    field: "value",
                    name: "John"
                }                               //And send this data to it
            ).done(                             //And when it's done
                function(data)
                {
                    $('#fromAjax').html(data);  //Update here with the response
                }
            );
        }
    </script>
  </head>
  <body>
    <input type="button" value = "use ajax", onclick="ajaxmagic()">
    <span id="fromAjax"></span>
  </body>
</html>

The above code will send a POST request to the page test.php.

Note: You can mix sessions with ajax and stuff if you want.

How do I...

1. How do I connect to the database?
2. How do I prevent SQL injection?
3. Why shouldn't I use Mysql_* functions?

... for these or any other, please make another questions. That's too much for this one.

@Marton had an important objection to the accepted answer on the grounds that the pipe creates a new collection on each change detection. I would instead create an HtmlService which provides a range of utility functions which the view can use as follows:

@Component({
  selector: 'app-myview',
  template: `<div *ngFor="let i of html.keys(items)">{{i + ' : ' + items[i]}}</div>`
})
export class MyComponent {
  items = {keyOne: 'value 1', keyTwo: 'value 2', keyThree: 'value 3'};
  constructor(private html: HtmlService){}
}

@Injectable()
export class HtmlService {
  keys(object: {}) {
    return Object.keys(object);
  }
  // ... other useful methods not available inside html, like isObject(), isArray(), findInArray(), and others...
}

I had the same problem with a big project with many submodules. Based on the answers of Chris Johnsen here and VonC here I build a short bash script which iterates through all existing gitlink entries and adds them as proper submodules.

#!/bin/bash

# Read all submodules in current git
MODULES=`git ls-files --stage | grep 160000`

# Iterate through every submodule path
while read -r MOD; do
  # extract submodule path (split line at whitespace and take string with index 3)
  ARRIN=(${MOD})
  MODPATH=${ARRIN[3]}

  # grep module url from .git file in submodule path
  MODURL=`grep "url = " $MODPATH/.git/config`
  MODURL=${MODURL##*=}

  # echo path and url for information
  echo $MODPATH
  echo $MODURL

  # remove existing entry in submodule index
  git rm --cached $MODPATH
  # add new entry in submodule index
  git submodule add $MODURL $MODPATH
done <<< "$MODULES"

This fixed it for me, I hope it is of any help.

Since $.getJSON is async, I think your console.log(list.length); code is firing before your array has been populated. To correct this put your console.log statement inside your callback:

var list = new Array();
$.getJSON("json.js", function(data) {
    $.each(data, function(i, item) {
        console.log(item.text);
        list.push(item.text);
    });
    console.log(list.length);
});

to leave the file in the repo but ignore future changes to it:

git update-index --assume-unchanged <file>

and to undo this:

git update-index --no-assume-unchanged <file>

to find out which files have been set this way:

git ls-files -v|grep '^h'

User-specific settings are saved in the user's Application Data folder for that application. Look for a user.config file.

I don't know what you expected, since users often don't even have write access to the executable directory in the first place.

You can read database value in to a variable and then set the variable as follows

$app_container->assign('checked_flag', $db_data=='0'  ? '' : 'checked');

And in html you can just use the checked_flag variable as follows

<input type="checkbox" id="chk_test" name="chk_test" value="1" {checked_flag}>

I believe prestomanifesto was on the right track. It depends on what kind of element it is. You would need to use element.get_attribute('value') for input elements and element.text to return the text node of an element.

You could check the WebElement object with element.tag_name to find out what kind of element it is and return the appropriate value.

This should help you figure out:

driver = webdriver.Firefox()
driver.get('http://www.w3c.org')
element = driver.find_element_by_name('q')
element.send_keys('hi mom')

element_text = element.text
element_attribute_value = element.get_attribute('value')

print element
print 'element.text: {0}'.format(element_text)
print 'element.get_attribute(\'value\'): {0}'.format(element_attribute_value)
driver.quit()

I haven't used Angular, but reading the link above, it seems that you're trying to code for something that you don't need to handle. You make changes to state in your React component hierarchy (via this.setState()) and React will cause your component to be re-rendered (effectively 'listening' for changes). If you want to 'listen' from another component in your hierarchy then you have two options:

1. Pass handlers down (via props) from a common parent and have them update the parent's state, causing the hierarchy below the parent to be re-rendered.
2. Alternatively, to avoid an explosion of handlers cascading down the hierarchy, you should look at the flux pattern, which moves your state into data stores and allows components to watch them for changes. The Fluxxor plugin is very useful for managing this.

I came across this myself. I used .on so it looks a bit different but I did this:

 $('#element').on('keypress', function() {
   //code to be executed
 }).on('keydown', function(e) {
   if (e.keyCode==8)
     $('element').trigger('keypress');
 });

Adding my Work Around here. I needed to delete ssn typed by user so i did this in jQuery

  $(this).bind("keydown", function (event) {
        // Allow: backspace, delete
        if (event.keyCode == 46 || event.keyCode == 8) 
        {
            var tempField = $(this).attr('name');
            var hiddenID = tempField.substr(tempField.indexOf('_') + 1);
            $('#' + hiddenID).val('');
            $(this).val('')
            return;
        }  // Allow: tab, escape, and enter
        else if (event.keyCode == 9 || event.keyCode == 27 || event.keyCode == 13 ||
        // Allow: Ctrl+A
        (event.keyCode == 65 && event.ctrlKey === true) ||
        // Allow: home, end, left, right
        (event.keyCode >= 35 && event.keyCode <= 39)) {
            // let it happen, don't do anything
            return;
        }
        else 
        {
            // Ensure that it is a number and stop the keypress
            if (event.shiftKey || (event.keyCode < 48 || event.keyCode > 57) &&       (event.keyCode < 96 || event.keyCode > 105)) 
            {
                event.preventDefault();
            }
        }
    });

Just wanted to summarize all the correct answers above in short. Because I had to spend lot of time to figure out which answer resolves the issue and what's going on behind the scenes.

There seems to be two problems of fieldset with bootstrap:

1. The bootstrap sets the width to the legend as 100%. That is why it overlays the top border of the fieldset.
2. There's a bottom border for the legend.

So, all we need to fix this is set the legend width to auto as follows:

legend.scheduler-border {
   width: auto; // fixes the problem 1
   border-bottom: none; // fixes the problem 2
}

I think that your problem is in the location of the image. You shall place it in your source, and then use it like this:

  JButton button = new JButton();
  try {
    Image img = ImageIO.read(getClass().getResource("resources/water.bmp"));
    button.setIcon(new ImageIcon(img));
  } catch (Exception ex) {
    System.out.println(ex);
  }

In this example, it is assumed that image is in src/resources/ folder.

Use:

((Long) userService.getAttendanceList(currentUser)).intValue();

instead.

The .intValue() method is defined in class Number, which Long extends.

• Official Python .msi installers are designed to replace:

  • any previous micro release (in x.y.z, z is "micro") because they are guaranteed to be backward-compatible and binary-compatible
  • a "snapshot" (built from source) installation with any micro version

• A snapshot installer is designed to replace any snapshot with a lower micro version.

(See responsible code for 2.x, for 3.x)

Any other versions are not necessarily compatible and are thus installed alongside the existing one. If you wish to uninstall the old version, you'll need to do that manually. And also uninstall any 3rd-party modules you had for it:

• If you installed any modules from bdist_wininst packages (Windows .exes), uninstall them before uninstalling the version, or the uninstaller might not work correctly if it has custom logic
• modules installed with setuptools/pip that reside in Lib\site-packages can just be deleted afterwards
• packages that you installed per-user, if any, reside in %APPDATA%/Python/PythonXY/site-packages and can likewise be deleted

For anyone stumbling over here like me - I had success with escaping the semicolon and the newline:

First step: the semicolon. This way, we do not break the ssh command:

ssh <host> echo test\;ls
                    ^ backslash!

Listed the remote hosts /home directory (logged in as root), whereas

ssh <host> echo test;ls
                    ^ NO backslash

listed the current working directory.

Next step: breaking up the line:

                      v another backslash!
ssh <host> echo test\;\
ls

This again listed the remote working directory - improved formatting:

ssh <host>\
  echo test\;\
  ls

If really nicer than here document or quotes around broken lines - well, not me to decide...

(Using bash, Ubuntu 14.04 LTS.)

.row-eq-height {
display: -webkit-box;
display: -webkit-flex;
display: -ms-flexbox;
display:         flex;
 }

From:

http://getbootstrap.com.vn/examples/equal-height-columns/equal-height-columns.css

They might be just a \r or a \n. I just checked and the text visualizer in VS 2010 displays both as newlines as well as \r\n.

This string

string test = "blah\r\nblah\rblah\nblah";

Shows up as

blah
blah
blah
blah

in the text visualizer.

So you could try

string modifiedString = originalString
    .Replace(Environment.NewLine, "<br />")
    .Replace("\r", "<br />")
    .Replace("\n", "<br />");

I had this problem and changing Extended Properties to HTML Import fixed it as per this post by Marcus Miris:

strCon = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & importedFilePathAndName _
         & ";Extended Properties=""HTML Import;HDR=No;IMEX=1"";"

Here's my short summary.

If you want to write a unit test, don't use a Spring applicationContext because you don't want any real dependencies injected in the class you are unit testing. Instead use mocks, either with the @RunWith(MockitoJUnitRunner.class) annotation on top of the class, or with MockitoAnnotations.initMocks(this) in the @Before method.

If you want to write an integration test, use:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("yourTestApplicationContext.xml")

To set up your application context with an in-memory database for example. Normally you don't use mocks in integration tests, but you could do it by using the MockitoAnnotations.initMocks(this) approach described above.

Update for RxJS 6 (April 2018)

It is now perfectly fine to import directly from rxjs. (As can be seen in Angular 6+). Importing from rxjs/operators is also fine and it is actually no longer possible to import operators globally (one of major reasons for refactoring rxjs 6 and the new approach using pipe). Thanks to this treeshaking can now be used as well.

Sample code from rxjs repo:

import { Observable, Subject, ReplaySubject, from, of, range } from 'rxjs';
import { map, filter, switchMap } from 'rxjs/operators';

range(1, 200)
  .pipe(filter(x => x % 2 === 1), map(x => x + x))
  .subscribe(x => console.log(x));

Backwards compatibility for rxjs < 6?

rxjs team released a compatibility package on npm that is pretty much install & play. With this all your rxjs 5.x code should run without any issues. This is especially useful now when most of the dependencies (i.e. modules for Angular) are not yet updated.

There are other database systems, such as document stores, key value stores, columnar stores, object oriented databases. These are databases too but they are not based on relations (relational theory) ie they are not relational database systems.

So there are lot of differences. Database management system is the name for all databases.

I think I might have been overthinking this. One way I've come up with that does the job, is simply to have a global variable, that accumulates the diagnostic data.

Somthing like this:

log1 = dict()
class TestBar(unittest.TestCase):
    def runTest(self):
        for t1, t2 in testdata:
            f = Foo(t1) 
            if f.bar(t2) != 2: 
                log1("TestBar.runTest") = (f, t1, t2)
                self.fail("f.bar(t2) != 2")

Thanks for the replies. They have given me some alternative ideas for how to record information from unit tests in python.

My solution:

I have created wrapper over Object.assign to fix typing issues.

export function assign<T>(...args: T[] | Partial<T>[]): T {
  return Object.assign.apply(Object, [{}, ...args]);
}

Usage:

env.base.ts

export interface EnvironmentValues {
export interface EnvironmentValues {
  isBrowser: boolean;
  apiURL: string;
}

export const enviromentBaseValues: Partial<EnvironmentValues> = {
  isBrowser: typeof window !== 'undefined',
};

export default enviromentBaseValues;

env.dev.ts

import { EnvironmentValues, enviromentBaseValues } from './env.base';
import { assign } from '../utilities';

export const enviromentDevValues: EnvironmentValues = assign<EnvironmentValues>(
  {
    apiURL: '/api',
  },
  enviromentBaseValues
);

export default enviromentDevValues;

function generatePass(pLength){

    var keyListAlpha="abcdefghijklmnopqrstuvwxyz",
        keyListInt="123456789",
        keyListSpec="!@#_",
        password='';
    var len = Math.ceil(pLength/2);
    len = len - 1;
    var lenSpec = pLength-2*len;

    for (i=0;i<len;i++) {
        password+=keyListAlpha.charAt(Math.floor(Math.random()*keyListAlpha.length));
        password+=keyListInt.charAt(Math.floor(Math.random()*keyListInt.length));
    }

    for (i=0;i<lenSpec;i++)
        password+=keyListSpec.charAt(Math.floor(Math.random()*keyListSpec.length));

    password=password.split('').sort(function(){return 0.5-Math.random()}).join('');

    return password;
}

dataString suggests the data is formatted in a string (and maybe delimted by a character).

$data = explode(",", $_POST['data']);
foreach($data as $d){
     echo $d;
}

if dataString is not a string but infact an array (what your question indicates) use JSON.

In MySql, you can get 10 rows starting from row 20 using:

SELECT * FROM Reflow  
WHERE ReflowProcessID = somenumber
ORDER BY ID DESC
LIMIT 10 OFFSET 20 --Equivalent to LIMIT 20, 10

I faced this issue on GCP while deploying wordpress in the App Engine Standard environment. This solved it :

sudo apt-get install php7.2-zip

Please see this Question

You can only replace a "dynamically added fragment".

So, if you want to add a dynamic fragment, see this example.

This is how it worked for me:

• Make sure composer is installed without no errors.

• Open "System Properties" on windows and go to the "Advanced" tab. (You can just press the windows button on your keyboard and type in "Edit the system environment variables`

• "Environment variables"

• Under "System variables" Edit "PATH"

• Click on "New".

• Type in: C:\ProgramData\ComposerSetup\bin\composer.phar

• Close all folders & CMDs + restart you WAMP server.

• Go to whatever directory you want to install a package in and type in

  composer.phar create-project slim/slim-skeleton

for example.

You can use switch-case fall through by omitting the break; statement.

char c = /* whatever */;

switch(c) {
    case 'a':
    case 'A':
        //get the 'A' image;
        break;
    case 'b':
    case 'B':
        //get the 'B' image;
        break;
    // (...)
    case 'z':
    case 'Z':
        //get the 'Z' image;
        break;
}

...or you could just normalize to lower case or upper case before switching.

char c = Character.toUpperCase(/* whatever */);

switch(c) {
    case 'A':
        //get the 'A' image;
        break;
    case 'B':
        //get the 'B' image;
        break;
    // (...)
    case 'Z':
        //get the 'Z' image;
        break;
}

Type info variables to list "All global and static variable names".

Type info locals to list "Local variables of current stack frame" (names and values), including static variables in that function.

Type info args to list "Arguments of the current stack frame" (names and values).

I think you should avoid writing side-effecting method. Return true or false from your method and you can check these methods in unit tests.

This is the one I use:

set statusline=
set statusline+=%7*\[%n]                                  "buffernr
set statusline+=%1*\ %<%F\                                "File+path
set statusline+=%2*\ %y\                                  "FileType
set statusline+=%3*\ %{''.(&fenc!=''?&fenc:&enc).''}      "Encoding
set statusline+=%3*\ %{(&bomb?\",BOM\":\"\")}\            "Encoding2
set statusline+=%4*\ %{&ff}\                              "FileFormat (dos/unix..) 
set statusline+=%5*\ %{&spelllang}\%{HighlightSearch()}\  "Spellanguage & Highlight on?
set statusline+=%8*\ %=\ row:%l/%L\ (%03p%%)\             "Rownumber/total (%)
set statusline+=%9*\ col:%03c\                            "Colnr
set statusline+=%0*\ \ %m%r%w\ %P\ \                      "Modified? Readonly? Top/bot.

Highlight on? function:

function! HighlightSearch()
  if &hls
    return 'H'
  else
    return ''
  endif
endfunction

Each cell in the array is treated as unsigned int:

private int unsignedIntFromByteArray(byte[] bytes) {
int res = 0;
if (bytes == null)
    return res;


for (int i=0;i<bytes.length;i++){
    res = res | ((bytes[i] & 0xff) << i*8);
}
return res;
}

In R, whether a number is numeric or integer can be determined by class function. Generally all numbers are stored as numeric and to explicitly define a number as integer we need to specify 'L' after the number.

Example:

x <- 1

class(x)

[1] "numeric"

x <- 1L

class(x)

[1] "integer"

I hope this is what was needed. Thanks :)

Just searched for the docs, and found this:

Containment Operator: The in operator performs containment test. It returns true if the left operand is contained in the right:

{# returns true #}

{{ 1 in [1, 2, 3] }}

{{ 'cd' in 'abcde' }}

Use r.URL.Query() when you appending to existing query, if you are building new set of params use the url.Values struct like so

package main

import (
    "fmt"
    "log"
    "net/http"
    "net/url"
    "os"
)

func main() {
    req, err := http.NewRequest("GET","http://api.themoviedb.org/3/tv/popular", nil)
    if err != nil {
        log.Print(err)
        os.Exit(1)
    }

    // if you appending to existing query this works fine 
    q := req.URL.Query()
    q.Add("api_key", "key_from_environment_or_flag")
    q.Add("another_thing", "foo & bar")

    // or you can create new url.Values struct and encode that like so
    q := url.Values{}
    q.Add("api_key", "key_from_environment_or_flag")
    q.Add("another_thing", "foo & bar")

    req.URL.RawQuery = q.Encode()

    fmt.Println(req.URL.String())
    // Output:
    // http://api.themoviedb.org/3/tv/popularanother_thing=foo+%26+bar&api_key=key_from_environment_or_flag
}

Actually what happens is when you use postfix i.e. i++, the initial value of i is used for returning rather than the incremented one. After this the value of i is increased by 1. And this happens with any statement that uses i++, i.e. first initial value of i is used in the expression and then it is incremented.

And the exact opposite happens in prefix. If you would have returned ++i, then the incremented value i.e. 11 is returned, which is because adding 1 is performed first and then it is returned.

You must specify the file to be downloaded (attachment) by the client in the http header:

Response.ContentType = "application/vnd.ms-excel"
Response.AppendHeader "content-disposition", "attachment: filename=excelTest.xls"

I animated fading in of Recyclerview items when they first appear as shown in the code below. Perhaps this will be of use to someone.

private final static int FADE_DURATION = 1000; //FADE_DURATION in milliseconds

@Override
public void onBindViewHolder(ViewHolder holder, int position) {

    holder.getTextView().setText("some text");

    // Set the view to fade in
    setFadeAnimation(holder.itemView);            
}

private void setFadeAnimation(View view) {
    AlphaAnimation anim = new AlphaAnimation(0.0f, 1.0f);
    anim.setDuration(FADE_DURATION);
    view.startAnimation(anim);
}

You can also replace setFadeAnimation() with the following setScaleAnimation() to animate appearance of items by scaling them from a point:

private void setScaleAnimation(View view) {
    ScaleAnimation anim = new ScaleAnimation(0.0f, 1.0f, 0.0f, 1.0f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
    anim.setDuration(FADE_DURATION);
    view.startAnimation(anim);
}

The code above has some warts in so far as when you scroll the RecyclerView items always fade or scale. If you wish you can add code to just allow the animation to happen when the fragment or activity containing the RecyclerView is first created (e.g. get the system time on creation and only allow animation for the first FADE_DURATION milliseconds).

You need to run

php artisan migrate:rollback

if that also fails just go in and drop all the tables which you may have to do as it seems your migration table is messed up or your user table when you ran a previous rollback did not drop the table.

EDIT:

The reason this happens is that you ran a rollback previously and it had some error in the code or did not drop the table. This still however messes up the laravel migration table and as far as it's concerned you now have no record of pushing the user table up. The user table does already exist however and this error is throw.

As per different sources, I think the minimum length in E-164 format depends on country to country. For eg:

• For Israel: The minimum phone number length (excluding the country code) is 8 digits. - Official Source (Country Code 972)

• For Sweden : The minimum number length (excluding the country code) is 7 digits. - Official Source? (country code 46)

• For Solomon Islands its 5 for fixed line phones. - Source (country code 677)

... and so on. So including country code, the minimum length is 9 digits for Sweden and 11 for Israel and 8 for Solomon Islands.

Edit (Clean Solution): Actually, Instead of validating an international phone number by having different checks like length etc, you can use the Google's libphonenumber library. It can validate a phone number in E164 format directly. It will take into account everything and you don't even need to give the country if the number is in valid E164 format. Its pretty good! Taking an example:

String phoneNumberE164Format = "+14167129018"
PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
    PhoneNumber phoneNumberProto = phoneUtil.parse(phoneNumberE164Format, null);
    boolean isValid = phoneUtil.isValidNumber(phoneNumberProto); // returns true if valid
    if (isValid) {
        // Actions to perform if the number is valid
    } else {
        // Do necessary actions if its not valid 
    }
} catch (NumberParseException e) {
    System.err.println("NumberParseException was thrown: " + e.toString());
}

If you know the country for which you are validating the numbers, you don;t even need the E164 format and can specify the country in .parse function instead of passing null.

I think may be more automatic, grunt task usemin take care to do all this jobs for you, only need some configuration:

https://stackoverflow.com/a/33481683/1897196

Instead of saving it to the database, save it to a file and then call it later.

What many php apps do (like sugarcrm) is to just use var_export to echo all the data of the array to a file. This is what I use to save my configurations data:

private function saveConfig() {
    file_put_contents($this->_data['pathtocompileddata'],'<?php' . PHP_EOL . '$acs_confdata = ' . var_export($this->_data,true) . ';');        
}

I think this is a better way to save your data!

It would be good to know what your purpose is, why you want to initialize the keys in the first place. I am not sure you need to do that at all.

1) If you want to count the number of occurrences of keys, you can just do:

Definition = {}
# ...
Definition[key] = Definition.get(key, 0) + 1

2) If you want to get None (or some other value) later for keys that you did not encounter, again you can just use the get() method:

Definition.get(key)  # returns None if key not stored
Definition.get(key, default_other_than_none)

3) For all other purposes, you can just use a list of the expected keys, and check if the keys found later match those.

For example, if you only want to store values for those keys:

expected_keys = ['apple', 'banana']
# ...
if key_found in expected_keys:
    Definition[key_found] = value

Or if you want to make sure all expected keys were found:

assert(all(key in Definition for key in expected_keys))

If the API says to use HTTP Basic authentication, then you need to add an Authorization header to your request. I'd alter your code to look like this:

    WebRequest req = WebRequest.Create(@"https://sub.domain.com/api/operations?param=value&param2=value");
    req.Method = "GET";
    req.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes("username:password"));
    //req.Credentials = new NetworkCredential("username", "password");
    HttpWebResponse resp = req.GetResponse() as HttpWebResponse;

Replacing "username" and "password" with the correct values, of course.

Using .one ensures this is done only once and not repeatedly.

$(window).one("focus", function() {
    localStorage.clear();
});

It is okay to put several document.ready event listeners (if you need other events to execute multiple times) as long as you do not overdo it, for the sake of readability.

.one is especially useful when you want local storage to be cleared only once the first time a web page is opened or when a mobile application is installed the first time.

   // Fired once when document is ready
   $(document).one('ready', function () {
       localStorage.clear();
   });

mysql -u root -P 4406 -h localhost --protocol=tcp -p

Remember to change the user, port and host so that it matches your configurations. The -p flag is required if your database user is configured with a password

It helped my case to install the right curl version

sudo apt-get install php5-curl

With the drag and drop feature you will lose all the metadata of the photos.

I've created a project that make it really easy to import assets to the simulator: MBAssetsImporter.

It enables you to import both videos and photos while preserving all the original metadata of the files.

You can access tempfile in Spring by casting if the class of interface MultipartFile is CommonsMultipartFile.

public File getTempFile(MultipartFile multipartFile)
{
    CommonsMultipartFile commonsMultipartFile = (CommonsMultipartFile) multipartFile;
    FileItem fileItem = commonsMultipartFile.getFileItem();
    DiskFileItem diskFileItem = (DiskFileItem) fileItem;
    String absPath = diskFileItem.getStoreLocation().getAbsolutePath();
    File file = new File(absPath);

    //trick to implicitly save on disk small files (<10240 bytes by default)
    if (!file.exists()) {
        file.createNewFile();
        multipartFile.transferTo(file);
    }

    return file;
}

To get rid of the trick with files less than 10240 bytes maxInMemorySize property can be set to 0 in @Configuration @EnableWebMvc class. After that, all uploaded files will be stored on disk.

@Bean(name = "multipartResolver")
    public CommonsMultipartResolver createMultipartResolver() {
        CommonsMultipartResolver resolver = new CommonsMultipartResolver();
        resolver.setDefaultEncoding("utf-8");
        resolver.setMaxInMemorySize(0);
        return resolver;
    }

I'm not sure what you're trying to do, but here's something to consider: c(); won't do anything. c is an instance of the class checkbox and not a method to be called. So consider this:

public class FirstWindow extends JFrame {      public FirstWindow() {         checkbox c = new checkbox();         c.yourMethod(yourParameters); // call the method you made in checkbox     } }  public class checkbox extends JFrame {      public checkbox(yourParameters) {          // this is the constructor method used to initialize instance variables     }      public void yourMethod() // doesn't have to be void     {         // put your code here     } } 

str_replace('"', "", $string);
str_replace("'", "", $string);

I assume you mean quotation marks?

Otherwise, go for some regex, this will work for html quotes for example:

preg_replace("/<!--.*?-->/", "", $string);

C-style quotes:

preg_replace("/\/\/.*?\n/", "\n", $string);

CSS-style quotes:

preg_replace("/\/*.*?\*\//", "", $string);

bash-style quotes:

preg-replace("/#.*?\n/", "\n", $string);

Etc etc...

• Achartengine: I have used this. Although for real time graph this might not give good performance if you do not tweak properly.

Two ways:

1. Edit the properties of the service and set the Log On user. The appropriate right will be automatically assigned.

2. Set it manually: Go to Administrative Tools -> Local Security Policy -> Local Policies -> User Rights Assignment. Edit the item "Log on as a service" and add your domain user there.

Recently when working on a web app for a client, I noticed that any click events added to a non-anchor element didn't work on the iPad or iPhone. All desktop and other mobile devices worked fine - but as the Apple products are the most popular mobile devices, it was important to get it fixed.

Turns out that any non-anchor element assigned a click handler in jQuery must either have an onClick attribute (can be empty like below):

onClick=""

OR

The element css needs to have the following declaration:

cursor:pointer

Strange, but that's what it took to get things working again!

An old question, but I'll answer anyway. The answer to the actual question asked is that the bare return is redundant and should be left out.

Furthermore, the suggested value is false for the following reason:

if (ret<0) return;

Redefining a C reserved word as a macro is a bad idea on the face of it, but this particular suggestion is simply unsupportable, both as an argument and as code.

So I found a solution. I created an angularJS service, we'll call it MyDataRepository and I created a module for it. I then serve up this javascript file from my server-side controller:

HTML:

<script src="path/myData.js"></script>

Server-side:

@RequestMapping(value="path/myData.js", method=RequestMethod.GET)
public ResponseEntity<String> getMyDataRepositoryJS()
{
    // Populate data that I need into a Map
    Map<String, String> myData = new HashMap<String,String>();
    ...
    // Use Jackson to convert it to JSON
    ObjectMapper mapper = new ObjectMapper();
    String myDataStr = mapper.writeValueAsString(myData);

    // Then create a String that is my javascript file
    String myJS = "'use strict';" +
    "(function() {" +
    "var myDataModule = angular.module('myApp.myData', []);" +
    "myDataModule.service('MyDataRepository', function() {" +
        "var myData = "+myDataStr+";" +
        "return {" +
            "getData: function () {" +
                "return myData;" +
            "}" +
        "}" +
    "});" +
    "})();"

    // Now send it to the client:
    HttpHeaders responseHeaders = new HttpHeaders();
    responseHeaders.add("Content-Type", "text/javascript");
    return new ResponseEntity<String>(myJS , responseHeaders, HttpStatus.OK);
}

I can then inject MyDataRepository where ever I need it:

someOtherModule.service('MyOtherService', function(MyDataRepository) {
    var myData = MyDataRepository.getData();
    // Do what you have to do...
}

This worked great for me, but I am open to any feedback if anyone has any. }

Here an alternative using SUBSTRING

SELECT
            SUBSTRING([Field], LEN([Field]) - 2, 3) [Right3],
            SUBSTRING([Field], 0, LEN([Field]) - 2) [TheRest]
    FROM 
            [Fields]

with fiddle

item = objects.Find(obj => obj.property==myValue);

I have used this small snippet. Might be slower but works every time.

for i in 'find . -type f -name "*.jar"'; do
    jar tvf $i | grep "com.foo.bar.MyClass.clss";
    if [ $? -eq 0 ]; then echo $i; fi;
done

It will not work for first position so better solution is :

if ($counter != 0 && $counter % 3 == 0) {
   echo 'image file';
}

Check it by yourself. I have tested it for adding class for every 4th element.

you can solve this, taking the input tag inside a div, then put the padding property on div tag. This work's for me...

Like this:

<div class="paded">
    <input type="text" />
</div>

and css:

.paded{
    padding-right: 20px;
}

No, there isn't a decent solution for body type, unless you're willing to cater only to those with bleeding-edge browsers.

Microsoft has WEFT, their own proprietary font-embedding technology, but I haven't heard it talked about in years, and I know no one who uses it.

I get by with sIFR for display type (headlines, titles of blog posts, etc.) and using one of the less-worn-out web-safe fonts for body type (like Trebuchet MS). If you're bored with all the web-safe fonts, you're probably defining the term too narrowly — look at this matrix of stock fonts that ship with major OSes and chances are you'll be able to find a font cascade that will catch nearly all web users.

For instance: font-family: "Lucida Grande", "Verdana", sans-serif is a common font cascade; OS X comes with Lucida Grande, but those with Windows will get Verdana, a web-safe font with letters of similar size and shape to Lucida Grande. Linux users will also get Verdana if they've installed the web-safe fonts package that exists in most distros' package managers, or else they'll fall back to an ordinary sans-serif.

What you missed is " " in postcode because it is a varchar.

There are two ways of inserting.

When you created a table Table created. and you add a row just after creating it, you can use the following method.

INSERT INTO table_name
VALUES (value1,value2,value3,...);

1 row created.

You've added so many tables, or it is saved and you are reopening it, you need to mention the table's column name too or else it will display the same error.

ERROR at line 2:
ORA-00984: column not allowed here


INSERT INTO table_name (column1,column2,column3,...)
VALUES (value1,value2,value3,...);

1 row created.

Oops... Misunderstood the question...

Pause is the way to go

Old answer:

you can pipe commands into your patch file...

try

build.bat < responsefile.txt

For top right corner try this:

position: absolute;
top: 0;
right: 0;

select * FROM (SELECT 
   ROW_NUMBER() OVER (ORDER BY sal desc),* AS ROWID, 
 FROM EMP ) EMP  where ROWID=5

greater then values find out

select * FROM (SELECT 
       ROW_NUMBER() OVER (ORDER BY sal desc),* AS ROWID, 
     FROM EMP ) EMP  where ROWID>5

less then values find out

select * FROM (SELECT 
       ROW_NUMBER() OVER (ORDER BY sal desc),* AS ROWID, 
     FROM EMP ) EMP  where ROWID=5

I would also suggest the following command if you are working on a local git repository or in a directory in which patch -p1 --merge < ... was applied.

grep -rnw . -e '^<<<<<<<$'

You tried to do a.setText(a1). a1 is an int value, but setText() requires a string value. For this reason you need use String.valueOf(a1) to pass the value of a1 as a String and not as an int to a.setText(), like so:

a.setText(String.valueOf(a1))

that was the exact solution to the problem with my case.

One liner is the best :

db.mycollection.find({ 'fieldname' : { $exists: true, $ne: null } });

Here,

mycollection : place your desired collection name

fieldname : place your desired field name

Explaination :

$exists : When is true, $exists matches the documents that contain the field, including documents where the field value is null. If is false, the query returns only the documents that do not contain the field.

$ne selects the documents where the value of the field is not equal to the specified value. This includes documents that do not contain the field.

So in your provided case following query going to return all the documents with imageurl field exists and having not null value:

db.mycollection.find({ 'imageurl' : { $exists: true, $ne: null } });

I write below code to remove the blank value in the array string.

string[] test={"1","","2","","3"};
test= test.Except(new List<string> { string.Empty }).ToArray();

You need to call self.a() to invoke a from b. a is not a global function, it is a method on the class.

You may want to read through the Python tutorial on classes some more to get the finer details down.

Merge two PDF byte arrays

If you are merging two byte arrays which contain PDF, this logic will not work. We need to use a third-party tool like PDFbox from Apache:

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
mergePdf.addSource(new ByteArrayInputStream(a));
mergePdf.addSource(new ByteArrayInputStream(b));
mergePdf.setDestinationStream(byteArrayOutputStream);
mergePdf.mergeDocuments();
c = byteArrayOutputStream.toByteArray();

For example folder named new under E: drive

type the command:

e:\cd new

e:\new\attrib *.* -s -h /s /d

and all the files and folders are un-hidden

The other answers work for real files, but if you need something that works for "file-like objects", try this:

# f is a file-like object. 
f.seek(0, os.SEEK_END)
size = f.tell()

It works for real files and StringIO's, in my limited testing. (Python 2.7.3.) The "file-like object" API isn't really a rigorous interface, of course, but the API documentation suggests that file-like objects should support seek() and tell().

Edit

Another difference between this and os.stat() is that you can stat() a file even if you don't have permission to read it. Obviously the seek/tell approach won't work unless you have read permission.

Edit 2

At Jonathon's suggestion, here's a paranoid version. (The version above leaves the file pointer at the end of the file, so if you were to try to read from the file, you'd get zero bytes back!)

# f is a file-like object. 
old_file_position = f.tell()
f.seek(0, os.SEEK_END)
size = f.tell()
f.seek(old_file_position, os.SEEK_SET)

You don't need to create your own class to return two different values. Just use a HashMap like this:

private HashMap<Toy, GameLevel> getToyAndLevelOfSpatial(Spatial spatial)
{
    Toy toyWithSpatial = firstValue;
    GameLevel levelToyFound = secondValue;

    HashMap<Toy,GameLevel> hm=new HashMap<>();
    hm.put(toyWithSpatial, levelToyFound);
    return hm;
}

private void findStuff()
{
    HashMap<Toy, GameLevel> hm = getToyAndLevelOfSpatial(spatial);
    Toy firstValue = hm.keySet().iterator().next();
    GameLevel secondValue = hm.get(firstValue);
}

You even have the benefit of type safety.

Dictionaries in Python are data structures that store key-value pairs. You can use them like associative arrays. Curly braces are used when declaring dictionaries:

d = {'One': 1, 'Two' : 2, 'Three' : 3 }
print d['Two'] # prints "2"

Curly braces are not used to denote control levels in Python. Instead, Python uses indentation for this purpose.

I think you really need some good resources for learning Python in general. See https://stackoverflow.com/q/175001/10077

Without explicitly defining the height I determined I need to apply the flex value to the parent and grandparent div elements...

<div style="display: flex;">
<div style="display: flex;">
 <img alt="No, he'll be an engineer." src="theknack.png" style="margin: auto;" />
</div>
</div>

If you're using a single element (e.g. dead-centered text in a single flex element) use the following:

align-items: center;
display: flex;
justify-content: center;

Use Convert.TryFromBase64String from C# 7.2

public static bool IsBase64String(string base64)
{
   Span<byte> buffer = new Span<byte>(new byte[base64.Length]);
   return Convert.TryFromBase64String(base64, buffer , out int bytesParsed);
}

I installed python2.7 to solve this issue. I wish can help you.

I believe once database rules are written accurately, it will be enough to protect your data. Moreover, there are guidelines that one can follow to structure your database accordingly. For example, making a UID node under users, and putting all under information under it. After that, you will need to implement a simple database rule as below

  "rules": {
    "users": {
      "$uid": {
        ".read": "auth != null && auth.uid == $uid",
        ".write": "auth != null && auth.uid == $uid"
      }
    }
  }
}

No other user will be able to read other users' data, moreover, domain policy will restrict requests coming from other domains. One can read more about it on Firebase Security rules

First and foremost, a RESTful web service is STATELESS (or in other words, SESSIONLESS). Therefore, a RESTful service does not have and should not have a concept of session or cookies involved. The way to do authentication or authorization in the RESTful service is by using the HTTP Authorization header as defined in the RFC 2616 HTTP specifications. Every single request should contain the HTTP Authorization header, and the request should be sent over an HTTPs (SSL) connection. This is the correct way to do authentication and to verify the authorization of requests in a HTTP RESTful web services. I have implemented a RESTful web service for the Cisco PRIME Performance Manager application at Cisco Systems. And as part of that web service, I have implemented authentication/authorization as well.

import pandas as pd

dataset = pd.read_csv("data.csv")

edit:

actually, you can just index the dataset like any old array.

dataset = pd.read_csv("data.csv")
first_value = dataset["column name"][0]

Archive.bulk is now deprecated, the new method to be used for this is glob:

var fileName =   'zipOutput.zip'
var fileOutput = fs.createWriteStream(fileName);

fileOutput.on('close', function () {
    console.log(archive.pointer() + ' total bytes');
    console.log('archiver has been finalized and the output file descriptor has closed.');
});

archive.pipe(fileOutput);
archive.glob("../dist/**/*"); //some glob pattern here
archive.glob("../dist/.htaccess"); //another glob pattern
// add as many as you like
archive.on('error', function(err){
    throw err;
});
archive.finalize();

I guess you are using Rails 4. If so, the needed parameters must be marked as required.

You might want to do it like this:

class UsersController < ApplicationController

  def create
    @user = User.new(user_params)
    # ...
  end

  private

  def user_params
    params.require(:user).permit(:username, :email, :password, :salt, :encrypted_password)
  end
end

Easy way with commons-io.

IOUtils.toString(request.getReader());

https://commons.apache.org/proper/commons-io/javadocs/api-2.5/org/apache/commons/io/IOUtils.html

Your regex ^[0-9] matches anything beginning with a digit, including strings like "1A". To avoid a partial match, append a $ to the end:

^[0-9]*$

This accepts any number of digits, including none. To accept one or more digits, change the * to +. To accept exactly one digit, just remove the *.

UPDATE: You mixed up the arguments to IsMatch. The pattern should be the second argument, not the first:

if (!System.Text.RegularExpressions.Regex.IsMatch(textbox.Text, "^[0-9]*$"))

CAUTION: In JavaScript, \d is equivalent to [0-9], but in .NET, \d by default matches any Unicode decimal digit, including exotic fare like ? (Myanmar 2) and ? (N'Ko 9). Unless your app is prepared to deal with these characters, stick with [0-9] (or supply the RegexOptions.ECMAScript flag).

Which specific index? If you want 'Add New' to be first on the dropdownlist you can add it though the code like this:

<asp:DropDownList ID="DropDownList1" AppendDataBoundItems="true" runat="server">
     <asp:ListItem Text="Add New" Value="0" />
</asp:DropDownList>

If you want to add it at a different index, maybe the last then try:

ListItem lst = new ListItem ( "Add New" , "0" );

DropDownList1.Items.Insert( DropDownList1.Items.Count-1 ,lst);

I've seen this kind of thing work in the wild:

<input type="button"  th:onclick="'javascript:getContactId(\'' + ${contact.id} + '\');'" />

You have to modify the control template instead of ItemsPanelTemplate:

<ItemsControl >
    <ItemsControl.Template>
        <ControlTemplate>
            <ScrollViewer x:Name="ScrollViewer" Padding="{TemplateBinding Padding}">
                <ItemsPresenter />
            </ScrollViewer>
        </ControlTemplate>
    </ItemsControl.Template>
</ItemsControl>

Maybe, your code does not working because StackPanel has own scrolling functionality. Try to use StackPanel.CanVerticallyScroll property.

Reread the error message. It says:

sh: mysql_config: not found

If you are on Ubuntu Natty, mysql_config belongs to package libmysqlclient-dev

for /f "tokens=* delims= " %%f in (myfile) do

This reads a file line-by-line, removing leading spaces (thanks, jeb).

set line=%%f

sets then the line variable to the line just read and

call :procesToken

calls a subroutine that does something with the line

:processToken

is the start of the subroutine mentioned above.

for /f "tokens=1* delims=/" %%a in ("%line%") do

will then split the line at /, but stopping tokenization after the first token.

echo Got one token: %%a

will output that first token and

set line=%%b

will set the line variable to the rest of the line.

if not "%line%" == "" goto :processToken

And if line isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.

OpenID and OAuth are each HTTP-based protocols for authentication and/or authorization. Both are intended to allow users to perform actions without giving authentication credentials or blanket permissions to clients or third parties. While they are similar, and there are proposed standards to use them both together, they are separate protocols.

OpenID is intended for federated authentication. A client accepts an identity assertion from any provider (although clients are free to whitelist or blacklist providers).

OAuth is intended for delegated authorization. A client registers with a provider, which provides authorization tokens which it will accept to perform actions on the user's behalf.

OAuth is currently better suited for authorization, because further interactions after authentication are built into the protocol, but both protocols are evolving. OpenID and its extensions could be used for authorization, and OAuth can be used for authentication, which can be thought of as a no-op authorization.

This is because of a higher JDK during compile time and lower JDK during runtime. So you just need to update your JDK version, possible to JDK 7

You may also check Unsupported major.minor version 51.0

If I understand your question correctly:

for elem in doc.findall('timeSeries/values/value'):
    print elem.get('dateTime'), elem.text

or if you prefer (and if there is only one occurrence of timeSeries/values:

values = doc.find('timeSeries/values')
for value in values:
    print value.get('dateTime'), elem.text

The findall() method returns a list of all matching elements, whereas find() returns only the first matching element. The first example loops over all the found elements, the second loops over the child elements of the values element, in this case leading to the same result.

I don't see where the problem with not finding timeSeries comes from however. Maybe you just forgot the getroot() call? (note that you don't really need it because you can work from the elementtree itself too, if you change the path expression to for example /timeSeriesResponse/timeSeries/values or //timeSeries/values)

More fast way using directly a no-string array but a string:

string[] StringSplit(string StringToSplit, string Delimitator)
{
    return StringToSplit.Split(new[] { Delimitator }, StringSplitOptions.None);
}

StringSplit("E' una bella giornata oggi", "giornata");
/* Output
[0] "E' una bella giornata"
[1] " oggi"
*/

You need to edit your hosts file on your Windows Virtual machine the same way you do for your local host machine:

C:\WINDOWS\system32\drivers\etc\hosts

And link your virtual hosts to 10.0.2.2, If you are just using localhost then replace

127.0.0.1 localhost with 10.0.2.2 localhost

For example:

10.0.2.2 localhost
10.0.2.2 local.site1.com
10.0.2.2 local.site2.com

This tells your virtual machine to point to your local machine for those domain names.

A trick I haven't seen on here yet that doesn't use extglob, find, or grep is to treat two file lists as sets and "diff" them using comm:

comm -23 <(ls) <(ls *Music*)

comm is preferable over diff because it doesn't have extra cruft.

This returns all elements of set 1, ls, that are not also in set 2, ls *Music*. This requires both sets to be in sorted order to work properly. No problem for ls and glob expansion, but if you're using something like find, be sure to invoke sort.

comm -23 <(find . | sort) <(find . | grep -i '.jpg' | sort)

Potentially useful.

I had the same problem, tried setting path variables and everything. What SDK manager needs is not the JDK, but the actual Java SE end user crap. Go to http://www.java.com/en/download/ie_manual.jsp?locale=en and download that. As soon as I finished installing that, it worked like a charm

Php has a super sexy function for this, just pass the array to it:

$json = json_encode($var);

$.ajax({
url:"Example.php",
type:"POST",
dataType : "json",
success:function(msg){
    console.info(msg);
}
});

simples :)

Here is a solution using an overlay that inhibits along with material design spinner that you configure one time in your app and you can call it from anywhere.

app.component.html

(put this somewhere at the root level of your html)

<div class="overlay" [style.height.px]="height" [style.width.px]="width" *ngIf="message.plzWait$ | async">
        <mat-spinner class="plzWait"  mode="indeterminate"></mat-spinner>
</div>

app.component.css

.plzWait{
  position: relative;
  left: calc(50% - 50px);
  top:50%;

}
.overlay{
  position: absolute;
  top:0px;
  left:0px;
  width: 100%;
  height: 100%;
  background: black;
  opacity: .5;
  z-index: 999999;
}

app.component.ts

height = 0;
width = 0;
constructor(
    private message: MessagingService
  }
ngOnInit() {
    this.height = document.body.clientHeight;
    this.width = document.body.clientWidth;
  }

messaging.service.ts

import { Injectable } from '@angular/core';
import { Subject } from 'rxjs';

@Injectable({
    providedIn: 'root',
  })
export class MessagingService {
    // Observable string sources
  private plzWaitObservable = new Subject<boolean>();


  // Public Observables you subscribe to
  public plzWait$ = this.plzWaitObservable.asObservable();

  public plzWait = (wait: boolean) => this.plzWaitObservable.next(wait);
}

Some other component

constructor(private message: MessagingService) { }
somefunction() {
    this.message.plzWait(true);
    setTimeout(() => {
            this.message.plzWait(false);
    }, 5000);
}

            xfbml      :true,      
            version    :'v2.1'
        });
    };
    (function(d, s, id) {
        var js, fjs = d.getElementsByTagName(s)[0];
        if(d.getElementById(id)) {
            return;
        }     
        js = d.createElement(s); 
        js.id = id;     
        js.src ="// connect.facebook.net/en_US /sdk.js";     
        fjs.parentNode.insertBefore(js, fjs);
    }
    (document,'script','facebook-jssdk'));
</script> 

From the documentation: The Facebook SDK for JavaScript doesn't have any standalone files that need to be downloaded or installed, instead you simply need to include a short piece of regular JavaScript in your HTML tha

Similar to tier777 here is a solution for a horizontal line:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:top="-1dp">
        <shape android:shape="line">
            <stroke
                android:width="1dp"
                android:color="#111"
                android:dashWidth="8dp"
                android:dashGap="2dp"
                />
            <solid android:color="@android:color/transparent" />
        </shape>
    </item>
</layer-list>

The clue is <item android:top="-1dp">.

In order to show dashed line on old devices (<= API 21) you should create a view with android:layerType="software" (see Android dashed line drawable potential ICS bug):

<?xml version="1.0" encoding="utf-8"?>
<View xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="@drawable/dashed_line"
    android:layerType="software"
    />

Also you can add the same view without android:layerType="software" to layout-v23 for better performance, but I am not sure it will work on all devices with API 23.

Remove the data attribute as you are not POSTING anything to the server (Your controller does not expect any parameters).

And in your AJAX Method you can use Razor and use @Url.Action rather than a static string:

$.ajax({
    url: '@Url.Action("FirstAjax", "AjaxTest")',
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: successFunc,
    error: errorFunc
});

From your update:

$.ajax({
    type: "POST",
    url: '@Url.Action("FirstAjax", "AjaxTest")',
    contentType: "application/json; charset=utf-8",
    data: { a: "testing" },
    dataType: "json",
    success: function() { alert('Success'); },
    error: errorFunc
});

Th easiest way to this is var id = $(this).val(); from inside an event like on change.

If the number of nesting levels is small, I use collections.defaultdict for this:

from collections import defaultdict

def nested_dict_factory(): 
  return defaultdict(int)
def nested_dict_factory2(): 
  return defaultdict(nested_dict_factory)
db = defaultdict(nested_dict_factory2)

db['new jersey']['mercer county']['plumbers'] = 3
db['new jersey']['mercer county']['programmers'] = 81

Using defaultdict like this avoids a lot of messy setdefault(), get(), etc.

I had from a totaly different reason the same notice "Value does not fall within the expected range" from the Visual studio 2008 while trying to use the: Tools -> Windows Embedded Silverlight Tools -> Update Silverlight For Windows Embedded Project.

After spending many ohurs I found out that the problem was that there wasn't a resource file and the update tool looks for the .RC file

Therefor the solution is to add to the resource folder a .RC file and than it works perfectly. I hope it will help someone out there

The FacetGrid plot does produce pretty small labels. While @paul-h has described the use of sns.set as a way to the change the font scaling, it may not be the optimal solution since it will change the font_scale setting for all plots.

You could use the seaborn.plotting_context to change the settings for just the current plot:

with sns.plotting_context(font_scale=1.5):
    sns.factorplot(x, y ...)

Sub TEST()
Dim value1 As String
Dim value2 As String
value1 = ThisWorkbook.Sheets(1).Range("A1").Value 'value from sheet1
value2 = ThisWorkbook.Sheets(2).Range("A1").Value 'value from sheet2
If value1 = value2 Then ThisWorkbook.Sheets(2).Range("L1").Value = value1 'or 2
End Sub

This will compare two sheets cells values and if they match place the value on sheet 2 in column L.

The tutorial is cheating because it is starting with a greyscale image encoded in RGB, so they are just slicing a single color channel and treating it as greyscale. The basic steps you need to do are to transform from the RGB colorspace to a colorspace that encodes with something approximating the luma/chroma model, such as YUV/YIQ or HSL/HSV, then slice off the luma-like channel and use that as your greyscale image. matplotlib does not appear to provide a mechanism to convert to YUV/YIQ, but it does let you convert to HSV.

Try using matplotlib.colors.rgb_to_hsv(img) then slicing the last value (V) from the array for your grayscale. It's not quite the same as a luma value, but it means you can do it all in matplotlib.

Background:

• http://matplotlib.sourceforge.net/api/colors_api.html
• http://en.wikipedia.org/wiki/HSL_and_HSV

Alternatively, you could use PIL or the builtin colorsys.rgb_to_yiq() to convert to a colorspace with a true luma value. You could also go all in and roll your own luma-only converter, though that's probably overkill.

In iOS10 there is new constant called UICollectionViewFlowLayout.automaticSize (formerly UICollectionViewFlowLayoutAutomaticSize), so instead:

self.flowLayout.estimatedItemSize = CGSize(width: 100, height: 100)

you can use this:

self.flowLayout.estimatedItemSize = UICollectionViewFlowLayout.automaticSize

It has better performance especially when cells in you collection view has constant wid

Accessing Flow Layout:

override func viewDidLoad() {
   super.viewDidLoad()

   if let flowLayout = collectionView?.collectionViewLayout as? UICollectionViewFlowLayout {
      flowLayout.estimatedItemSize = UICollectionViewFlowLayout.automaticSize
   }
}

Swift 5 Updated:

override func viewDidLoad() {
   super.viewDidLoad()

   if let flowLayout = collectionView?.collectionViewLayout as? UICollectionViewFlowLayout {
      flowLayout.estimatedItemSize = UICollectionViewFlowLayout.automaticSize
    }
}

If you look in the source code for $.fn.bind you will find that it's just an rewrite function for on:

    return this.on(types, null, data, fn);
}

this is what I do, python3.3. I was processing huge lists of sites, so failing on the timeout was vital for the job to run through the entire list.

command = "phantomjs --ignore-ssl-errors=true "+<your js file for phantom>
process = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE)

# make sure phantomjs has time to download/process the page
# but if we get nothing after 30 sec, just move on
try:
    output, errors = process.communicate(timeout=30)
except Exception as e:
    print("\t\tException: %s" % e)
    process.kill()

# output will be weird, decode to utf-8 to save heartache
phantom_output = ''
for out_line in output.splitlines():
    phantom_output += out_line.decode('utf-8')

The toString() method of Selenium's By-Class produces something like "By.xpath: //XpathFoo"

So you could take a substring starting at the colon with something like this:

String selector = divA.toString().substring(s.indexOf(":") + 2);

With this, you could find your element inside your other element with this:

WebElement input = driver.findElement( By.xpath( selector + "//input" ) );

Advantage: You have to search only once on the actual SUT, so it could give you a bonus in performance.

Disadvantage: Ugly... if you want to search for the parent element with css selectory and use xpath for it's childs, you have to check for types before you concatenate... In this case, Slanec's solution (using findElement on a WebElement) is much better.

You want the (standard) POSIXt type from base R that can be had in 'compact form' as a POSIXct (which is essentially a double representing fractional seconds since the epoch) or as long form in POSIXlt (which contains sub-elements). The cool thing is that arithmetic etc are defined on this -- see help(DateTimeClasses)

Quick example:

R> now <- Sys.time()
R> now
[1] "2009-12-25 18:39:11 CST"
R> as.numeric(now)
[1] 1.262e+09
R> now + 10  # adds 10 seconds
[1] "2009-12-25 18:39:21 CST"
R> as.POSIXlt(now)
[1] "2009-12-25 18:39:11 CST"
R> str(as.POSIXlt(now))
 POSIXlt[1:9], format: "2009-12-25 18:39:11"
R> unclass(as.POSIXlt(now))

Lastly, the zoo package is an extremely versatile and well-documented container for matrix with associated date/time indices.

You can use case-sensitive or case-insensitive comparison, depending what you need. Case-sensitive is like this:

if ([category isEqualToString:@"Some String"])
{
   // Both strings are equal without respect to their case.
}

Case-insensitive is like this:

if ([category compare:@"Some String" options:NSCaseInsensitiveSearch] == NSOrderedSame)
{
   // Both strings are equal with respect to their case.
}

For a 2d numpy array, simply use imshow() may help you:

import matplotlib.pyplot as plt
import numpy as np


def heatmap2d(arr: np.ndarray):
    plt.imshow(arr, cmap='viridis')
    plt.colorbar()
    plt.show()


test_array = np.arange(100 * 100).reshape(100, 100)
heatmap2d(test_array)

This code produces a continuous heatmap.

You can choose another built-in colormap from here.

how about:

scope.$watch(function() { 
   return { 
      a: thing-one, 
      b: thing-two, 
      c: red-fish, 
      d: blue-fish 
   }; 
}, listener...);

I think leverage this functionality using Java

long time= System.currentTimeMillis();

this will return current time in milliseconds mode . this will surely work

long time= System.currentTimeMillis();
android.util.Log.i("Time Class ", " Time value in millisecinds "+time);

Here is my logcat using the above function

05-13 14:38:03.149: INFO/Time Class(301): Time value in millisecinds 1368436083157

If you got any doubt with millisecond value .Check Here

EDIT : Time Zone I used to demo the code IST(+05:30) ,So if you check milliseconds that mentioned in log to match with time in log you might get a different value based your system timezone

EDIT: This is easy approach .but if you need time zone or any other details I think this won't be enough Also See this approach using android api support

Go to mirror.olnevhost.net/pub/apache/maven/binaries/ and check what is the latest tar.gz file

Supposing it is e.g. apache-maven-3.2.1-bin.tar.gz, from the command line; you should be able to simply do:

wget http://mirror.olnevhost.net/pub/apache/maven/binaries/apache-maven-3.2.1-bin.tar.gz

And then proceed to install it.

UPDATE: Adding complete instructions (copied from the comment below)

1. Run command above from the dir you want to extract maven to (e.g. /usr/local/apache-maven)

2. run the following to extract the tar:

   tar xvf apache-maven-3.2.1-bin.tar.gz
   

3. Next add the env varibles such as

   export M2_HOME=/usr/local/apache-maven/apache-maven-3.2.1

   export M2=$M2_HOME/bin

   export PATH=$M2:$PATH

4. Verify

   mvn -version
   

Embedded Emmet could do the trick:

1. Select text (optional)
2. Open command palette (usually Ctrl+Shift+P)
3. Execute Emmet: Wrap with Abbreviation
4. Enter a tag div (or an abbreviation .wrapper>p)
5. Hit Enter

Command can be assigned to a keybinding.

This thing even supports passing arguments:

{
    "key": "ctrl+shift+9",
    "command": "editor.emmet.action.wrapWithAbbreviation",
    "when": "editorHasSelection",
    "args": {
        "abbreviation": "span"
    }
},

Use it like this:

• span.myCssClass
• span#myCssId
• b
• b.myCssClass

Depending on whether your php setup allows fopen on URLs, you could also simply fopen the url with the get arguments in the string (such as http://example.com?variable=value )

Edit: Re-reading the question I'm not certain whether you're looking to pass variables or not - if you're not you can simply send the fopen request containg http://example.com/filename.xml - feel free to ignore the variable=value part

like said before best would be to set datatype of the column to nvarchar(max), but if that's not possible you can do the following using cast or convert:

-- create a test table 
create table test (
    a text
) 
-- insert test value
insert into test (a) values ('this is a text')
-- the following does not work !!!
update test set a = a + ' and a new text added'
-- but this way it works: 
update test set a = cast ( a as nvarchar(max))  + cast (' and a new text added' as nvarchar(max) )
-- test result
select * from test
-- column a contains:
this is a text and a new text added

hope that helps

This works for me without throwing an exception:

package com.sandbox;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class Sandbox {

    public static void main(String[] args) throws ParseException {
        SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd");
        Date parsed = format.parse("20110210");
        java.sql.Date sql = new java.sql.Date(parsed.getTime());
    }


}

isset($vars[1]) AND !empty($vars[1]) is equivalent to !empty($vars[1]).

I prepared simple code to show it empirically.

Last row is undefined variable.

+-----------+---------+---------+----------+---------------------+
| Var value | empty() | isset() | !empty() | isset() && !empty() |
+-----------+---------+---------+----------+---------------------+
| ''        | true    | true    | false    | false               |
| ' '       | false   | true    | true     | true                |
| false     | true    | true    | false    | false               |
| true      | false   | true    | true     | true                |
| array ()  | true    | true    | false    | false               |
| NULL      | true    | false   | false    | false               |
| '0'       | true    | true    | false    | false               |
| 0         | true    | true    | false    | false               |
| 0.0       | true    | true    | false    | false               |
| undefined | true    | false   | false    | false               |
+-----------+---------+---------+----------+---------------------+

And code

$var1 = "";
$var2 = " ";
$var3 = FALSE;
$var4 = TRUE;
$var5 = array();
$var6 = null;
$var7 = "0";
$var8 = 0;
$var9 = 0.0;

function compare($var)
{
    print(var_export($var, true) . "|" .
        var_export(empty($var), true) . "|" .
        var_export(isset($var), true) . "|" .
        var_export(!empty($var), true) . "|" .
        var_export(isset($var) && !empty($var), true) . "\n");
}

for ($i = 1; $i <= 9; $i++) {
    $var = 'var' . $i;
    compare($$var);
}

@print(var_export($var10, true) . "|" .
    var_export(empty($var10), true) . "|" .
    var_export(isset($var10), true) . "|" .
    var_export(!empty($var10), true) . "|" .
    var_export(isset($var10) && !empty($var10), true) . "\n");

Undefined variable must be evaluated outside function, because function itself create temporary variable in the scope itself.

var values = $("input[name='user_group']:checked").map(function(){
      return $(this).val();
    }).get();

This will give you all the values of the checked boxed in an array.

In addition to @Ceki 's answer, If you are using logback and setup a config file in your project (usually logback.xml), you can define the log to plot the stack trace as well using

<encoder>
    <pattern>%date |%-5level| [%thread] [%file:%line] - %msg%n%ex{full}</pattern> 
</encoder>

the %ex in pattern is what makes the difference

.NET's built-in flag enum operations are unfortunately quite limited. Most of the time users are left with figuring out the bitwise operation logic.

In .NET 4, the method HasFlag was added to Enum which helps simplify user's code but unfortunately there are many problems with it.

1. HasFlag is not type-safe as it accepts any type of enum value argument, not just the given enum type.
2. HasFlag is ambiguous as to whether it checks if the value has all or any of the flags provided by the enum value argument. It's all by the way.
3. HasFlag is rather slow as it requires boxing which causes allocations and thus more garbage collections.

Due in part to .NET's limited support for flag enums I wrote the OSS library Enums.NET which addresses each of these issues and makes dealing with flag enums much easier.

Below are some of the operations it provides along with their equivalent implementations using just the .NET framework.

Combine Flags

.NET             flags | otherFlags

Enums.NET flags.CombineFlags(otherFlags)

Remove Flags

.NET             flags & ~otherFlags

Enums.NET flags.RemoveFlags(otherFlags)

Common Flags

.NET             flags & otherFlags

Enums.NET flags.CommonFlags(otherFlags)

Toggle Flags

.NET             flags ^ otherFlags

Enums.NET flags.ToggleFlags(otherFlags)

Has All Flags

.NET             (flags & otherFlags) == otherFlags or flags.HasFlag(otherFlags)

Enums.NET flags.HasAllFlags(otherFlags)

Has Any Flags

.NET             (flags & otherFlags) != 0

Enums.NET flags.HasAnyFlags(otherFlags)

Get Flags

.NET

Enumerable.Range(0, 64)
  .Where(bit => ((flags.GetTypeCode() == TypeCode.UInt64 ? (long)(ulong)flags : Convert.ToInt64(flags)) & (1L << bit)) != 0)
  .Select(bit => Enum.ToObject(flags.GetType(), 1L << bit))`

Enums.NET flags.GetFlags()

I'm trying to get these improvements incorporated into .NET Core and maybe eventually the full .NET Framework. You can check out my proposal here.

Cookies that 'expire at end of the session' expire unpredictably from the user's perspective!

On iOS with Safari they expire whenever you switch apps!

On Android with Chrome they don't expire when you close the browser.

On Windows desktop running Chrome they expire when you close the browser. That's not when you close your website's tab; its when you close all tabs. Nor do they expire if there are any other browser windows open. If users run web apps as windows they might not even know they are browser windows. So your cookie's life depends on what the user is doing with some apparently unrelated app.

One example of usage for null values is when using a HashMap as a cache for results of an expensive operation (such as a call to an external web service) which may return null.

Putting a null value in the map then allows you to distinguish between the case where the operation has not been performed for a given key (cache.containsKey(someKey) returns false), and where the operation has been performed but returned a null value (cache.containsKey(someKey) returns true, cache.get(someKey) returns null).

Without null values, you would have to either put some special value in the cache to indicate a null response, or simply not cache that response at all and perform the operation every time.

Just in case, instead of [(ngModel)] you can use (input) (is fired when a user writes something in the input <textarea>) or (blur) (is fired when a user leaves the input <textarea>) event,

<textarea cols="30" rows="4" (input)="str = $event.target.value"></textarea>

If you want to get the inputs of that type with that class use:

$("input.myClass[type=checkbox]")

the [] selector syntax allows you to check against any of the elements attributes. Check out the spec for more details

In my case,

-Xms1024M -Xmx1024M is work

-Xms1024M -Xmx2048M result: Could not reserve enough space for object heap

after use JVM 64 bit, it allows using 2GB RAM, because I am using win server 2012

please see the available max heap size for JVM 32 bit on several OSs

https://www.codementor.io/@suryab/does-32-bit-or-64-bit-jvm-matter-anymore-w0sa2rk6z

On windows, Try using git bash and use your Linux commands there. Easy approach

chmod 400 *****.pem

ssh -i "******.pem" [email protected]

You can use Swift's round function to accomplish this.

To round a Double with 3 digits precision, first multiply it by 1000, round it and divide the rounded result by 1000:

let x = 1.23556789
let y = Double(round(1000*x)/1000)
print(y)  // 1.236

Other than any kind of printf(...) or String(format: ...) solutions, the result of this operation is still of type Double.

EDIT:
Regarding the comments that it sometimes does not work, please read this:

How about the Omondo Plugin for Eclipse. I have used it and I find it to be quite useful. Although if you are generating diagrams for large sources, you might have to start Eclipse with more memory.

ok, try to go to the home "user@user:~$ " (cd + enter key), and npm install -g your your_module.

update: a podfile.lock is necessary and should not be ignored by version control, it keeps track of the versions of libraries installed at a certain pod install. (It's similar to gemfile.lock and composer.lock for rails and php dependency management, respectively). To learn more please read the docs. Credit goes to cbowns.

In my case, what I did was that I was doing some house cleaning for my project (ie branching out the integration tests as a git submodule.. removing duplicate files etc).. and pushed the final result to a git remote repo.. all the clients who cloned my repo suffered from the above error. Inspired by Hlung's comment above, I realized that there were some dangling pod scripts that were attempting to run against some non-existent files. So I went to my target build phase, and deleted all the remaining phases that had anything to do with cocoa pods (and Hlung's comment he suggests deleting Copy Pods Manifest.lock and copy pod resources.. mine were named different maybe b/c I'm using Xcode 5.. the point being is to delete those dangling build phases)..

I'm getting the same error on Mac OS X 10.11.6:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

After a lot of agonizing and digging through advice here and in related questions, none of which seemed to fix the problem, I went back and deleted the installed folders, and just did brew install mysql.

Still getting the same error with most commands, but this works:

/usr/local/bin/mysqld

and returns:

/usr/local/bin/mysqld: ready for connections.

Version: '5.7.12' socket: '/tmp/mysql.sock' port: 3306 Homebrew

Beside rowid, you can define your own auto increment field but it is not recommended. It is always be better solution when we use rowid that is automatically increased.

The AUTOINCREMENT keyword imposes extra CPU, memory, disk space, and disk I/O overhead and should be avoided if not strictly needed. It is usually not needed.

Read here for detailed information.

var dictionary = (from x in y 
                  select new SomeClass
                  {
                      prop1 = value1,
                      prop2 = value2
                  }
                  ).ToDictionary(item => item.prop1);

That's assuming that SomeClass.prop1 is the desired Key for the dictionary.

The request object is not the session.

You want to use the session object to store. The session is added to the request and is were you want to persist data across requests. The session can be obtained from

HttpSession session = request.getSession(true);

Then you can use setAttribute or getAttribute on the session.

The following function permutates an array of any type and calls a specified callback function on each permutation found:

/*
  Permutate the elements in the specified array by swapping them
  in-place and calling the specified callback function on the array
  for each permutation.

  Return the number of permutations.

  If array is undefined, null or empty, return 0.

  NOTE: when permutation succeeds, the array should be in the original state
  on exit!
*/
  function permutate(array, callback) {
    // Do the actual permuation work on array[], starting at index
    function p(array, index, callback) {
      // Swap elements i1 and i2 in array a[]
      function swap(a, i1, i2) {
        var t = a[i1];
        a[i1] = a[i2];
        a[i2] = t;
      }

      if (index == array.length - 1) {
        callback(array);
        return 1;
      } else {
        var count = p(array, index + 1, callback);
        for (var i = index + 1; i < array.length; i++) {
          swap(array, i, index);
          count += p(array, index + 1, callback);
          swap(array, i, index);
        }
        return count;
      }
    }

    if (!array || array.length == 0) {
      return 0;
    }
    return p(array, 0, callback);
  }

If you call it like this:

  // Empty array to hold results
  var result = [];
  // Permutate [1, 2, 3], pushing every permutation onto result[]
  permutate([1, 2, 3], function (a) {
    // Create a copy of a[] and add that to result[]
    result.push(a.slice(0));
  });
  // Show result[]
  document.write(result);

I think it will do exactly what you need - fill an array called result with the permutations of the array [1, 2, 3]. The result is:

[[1,2,3],[1,3,2],[2,1,3],[2,3,1],[3,2,1],[3,1,2]]
